I loved the original Fletch with Chevy Chase and can't really see why he couldn't do it again. If not Chevy, then Robert Downey Jr would be perfect as a wise cracking half competant investigator et la Kiss Kiss, Bang Bang!

NO! Leave it alone, Chevy Chase is the only Fletch. If Robert Downey Jr were to do it I would be fine maybe Ryan Reynolds because of the similar height and physicality but anyone else no, especially not Zac Galifinakis, there were times in Due Date where I just wanted to throw something at the screen when he was on.
